Do I understand correctly that there is no restore token functionality 
available for plain XTestFake* calls, and you suggest not using the 
XTEST and using one of the following for mouse/keyboard control?

  * org.freedesktop.portal.RemoteDesktop.ConnectToEIS and use libei
    sendercontext
  * org.freedesktop.portal.RemoteDesktop.NotifyPointerMotionAbsolute /
    NotifyPointerButton /NotifyPointerAxisDiscrete /
    NotifyKeyboardKeycode / etc

I quickly tried the latter and it seems to work fine on OEL 10 as expected.


Thanks,
Alexander.
